    # Represents an HTML element
    # 
    # == Modifying HTML options
    # 
    # HTML options can normally be specified when creating the element.
    # However, if they need to be modified after the element has been created,
    # you can access the properties like so:
    # 
    #   m = Menu.new
    #   m[:style] = 'display: none;'
    # 
    # or for a menu bar:
    # 
    #   b = MenuBar.new
    #   b[:style] = 'display: none;'
